Abstract
산호가 제일 많이 함유한 산호석회암에서 인체에 유익한 수용성 산화 칼슘을 분리해내는 방법에 관한 것이다.It is a method for separating water-soluble calcium oxide, which is beneficial to the human body, from coral limestone, which is the most abundant coral.
Description
본 발명은 수억년전의 지질시대(地質時代)이래 산호초(珊瑚礁)와 산호사(砂)로 형성된 산호석회암으로부터 수용성 산화칼슘을 제조하는 방법에 관한 것이다.The present invention relates to a method for producing a water-soluble calcium oxide from coral limestone formed of coral reefs and coral sand since the geological age of hundreds of millions of years ago.
종래의 산화칼슘(생석회)제조 방법으로는 석회석을 배소로(焙燒爐)에서 1,200∼1,650℃등의 온도로 소성하여 산화칼슘을 얻는 방법이 있었으나 그렇게 얻어진 산화칼슘은 대기중에 방치하게 되면 수분과 탄산가스를 흡수하여 수산화칼슘(소석회)과 탄산칼슘으로 변하게되어 공업용으로만 사용하여 왔었다.Conventional methods of producing calcium oxide (lime lime) have been obtained by calcining limestone at roasting furnaces at temperatures of 1,200 to 1,650 ° C to obtain calcium oxide. It absorbed the gas and turned into calcium hydroxide (calcium lime) and calcium carbonate, which has been used only for industrial purposes.
또한 시멘트 제조공정에서도 석회석과 점토, 규석등을 분말화하여 로타리 킬른에서 약1,450℃로 가열 소성하여 시멘트 크링카로 만든 후 거기에 석고를 첨가한 다음 미분쇄하여 시멘트를 얻는 과정에서도 산화칼슘(생석회)를 얻을 수 있었다.In the cement manufacturing process, limestone, clay, and silica are powdered and calcined by heating at a rotary kiln at about 1,450 ° C to make cement clinker, and then, gypsum is added to the powder, and then pulverized to obtain cement. Could get.
상기 두가지 생석회 제조방법에 의하여 석회석에서 산화 칼슘을 얻기위해서는 온도에 의해 많은 영향이 미치는 것으로 알려져 왔다.그런데 상기와 같은 기존의 생석회(산화칼슘) 제조방법에 의해서는 양질의 제품을 대량으로 얻을 수 없는 결점이 있었다.In order to obtain calcium oxide from limestone by the two quick lime manufacturing method has been known to have a lot of influence by the temperature. However, by using the conventional quick lime (calcium oxide) manufacturing method as described above it is impossible to obtain a large amount of high quality products. There was a flaw.
상기와 같은 종래의 산화칼슘 제조과정의 결점을 개선하여 본 발명은 산호석회암에서 양질의 수용성 산화칼슘을 대량으로 얻고져하는 것이다.즉 산호석회암은 화석석회암중에 산호류가 가장 많이 함유된 석회암으로서, 이는 수많은 산호류와 석회조(石灰藻), 유공충, 패류등 석회석 생성의 중요한 역할을 하는 물질과 지질시대(地質時代) 이래 산호초 연변부에서 파도에 밀린 산호초의 파편과 산호사등이 혼합되어 생성된 화석이기 때문이다.(일본 백화사전 8권 246P 참조)By improving the drawbacks of the conventional calcium oxide manufacturing process as described above, the present invention is to obtain a large amount of high-quality water-soluble calcium oxide from coral limestone. That is, limestone is the limestone containing the most corals among the fossil limestone, It is a fossil made of a mixture of corals, limestones, poreworms, shellfish and other materials that play an important role in the formation of limestones and fragments of coral reefs and coral sand that have been pushed by the waves at the edge of coral reefs since the geological age. (Refer to Japanese Department of Art, Vol. 8, 246P)
이상의 생성과정으로 보아 산호석회암은 식물성 칼슘이 함유된 석회조(石灰藻)와 동물성 산호의 분비물의 산호잔해(殘骸)등 무수한 희귀원소와 칼슘 및 기타인체에 유익한 미네랄이 함유되어 있음을 알 수 있다.From the above process, coral limestone contains countless rare elements such as limestone containing vegetable calcium and coral debris of secretion of animal coral, and minerals useful for calcium and other human body. .
그러나 상기와 같은 미네랄을 함유한 산호 잔해로된 산호석회암은 900℃이상 1,450℃의 고온에서 직화에 의해 소성하게되면 탄화되어 모두 소실되기 때문에 본 발명에서는 산호석회암을 900℃이하의 온도에서 간접가열에 의해 소성하여 수용성 산화칼슘을 얻는 방법을 제공코저하는 것으로서 이를 상세히 설명하면 다음과 같다.However, in the present invention, coral limestone made of coral debris containing such minerals is carbonized when fired by direct fire at a temperature of 900 ° C. or higher and 1,450 ° C., so that the coral limestone is indirectly heated at a temperature of 900 ° C. or lower. By calcining by providing a method for obtaining a water-soluble calcium oxide as described in detail as follows.
내화연와로된 소성로 속에 층층이 로스터를 놓고 그 각각의 로스터 위에 코크스를 깐 후 그 위에 미세한 산호 석회암 입자를 올려 놓고 코크스를 점화한 다음 운모창을 통하여 내부상태를 관찰하면서 연소온도 조절용 팬(FAN)에 의해 내부온도를 700~900℃범위가 되도록 조절하면서 48~50시간 소성시킨 다음 냉각하여 경량의 산호석회암 크링카를 얻고 다시 상기 크링카에 활성탄소를 1:1로 혼합하여 4,000킬로헬츠~6,500킬로헬츠의 고주파로에서 700~900℃의 온도로 36~40시간동안 가열 소성한 후 자연 냉각한 다음, 세척 및 건조하여 미세분말기에서 분말화하여 수용성 산화칼슘을 얻는다.Lay a layered roaster in a fire-retardant kiln and place coke on each roaster, place fine coral limestone particles on it, ignite the coke, and observe the internal condition through the mica window. By firing for 48 to 50 hours while controlling the internal temperature to be in the 700 ~ 900 ℃ range and then cooled to obtain a lightweight coral limestone clinker and again mixed with activated carbon 1: 1 in the crinkka 4,000 kilos ~ 6,500 kilos After heating and baking for 36-40 hours at a temperature of 700 to 900 ° C. in Hetz's high frequency furnace, it is naturally cooled, washed and dried to be powdered in a fine powder to obtain water-soluble calcium oxide.
상기에서 내화연와속 가마의 로스터에 코크스를 깐 후 그 위에 산호석회암 입자를 깔고 가열 소성하는 이유는 산호석회암의 조직이 다공질이고 치밀하지 못하여 직화소성에 의하여는 모두 탄화 소실되기 때문에 로스터상에서 간접 소성하여 일단 크링카를 얻기 위한 것이며, 소성온도를 700~900℃로 하는 것은 900℃이상에서는 모두 탄화되어 소실되기 때문이고 700℃이하에서는 산화칼슘 크링카가 아예 형성되지 않거나 완전하게 형성되지 않기 때문이며, 48~50시간의 소성시간은 그 온도 범위에서 덜 소성되거나 탄화되지 않고 가장 적절한 크링카 상태가 되기 때문이며, 고주파로에서 활성탄소와 상기 얻어진 크링카를 혼합하여 가열하는 것은 상기 로스터에서 약간 덜 소성된 크링카를 고주파로에서 활성탄소와 혼합하여 소성하므로서 완전히 소성된 경량의 크링카를 얻기 위한 것이고 상기 고주파로에서의 주파수, 온도 및 시간과 크링카와 활성탄소의 배합비(1:1)등은 그 범위가 최종제품인 수용성 산화칼슘을 얻기에 가장 바람직한 조건이며 그 이하나 그 이상의 조건에서는 소성이 미완성되거나 탄화되어 소실되기 때문에 제한하는 조건이다.The reason for the above is to apply the coke to the roaster of the fire retardant kiln kiln and lay the calcined coral limestone particles on it.The reason for the heating and firing is that the tissue of the coral limestone is not porous and dense, so all carbonization is lost by the direct fire. First, to obtain the krinka, the firing temperature is 700 ~ 900 ℃ because all carbonized and disappeared at 900 ℃ or higher, and calcium oxide clinker is not formed at all or below 700 ℃ at all, 48 The firing time of ˜50 hours is less calcined or carbonized in the temperature range and becomes the most appropriate crinca state, and heating the mixture of activated carbon and the obtained crinca in a high frequency furnace is slightly less calcined in the roaster. Is fired by mixing with activated carbon in high frequency furnace The frequency, temperature and time in the high frequency furnace and the blending ratio of the krinka and activated carbon (1: 1) are the most preferable conditions for obtaining the water-soluble calcium oxide in the final product. Under the above conditions, the firing is limited because it is unfinished or carbonized.
이상과 같은 방법으로 얻어진 수용성 산화칼슘은 성분 분석결과 다음표1과 같은 성분을 함유하고 있음을 알았고 따라서 인체에 유익한 효과가 있음을 알 수 있었다.<표1>As a result of the component analysis, it was found that the water-soluble calcium oxide obtained by the above method contained the components shown in the following Table 1, and thus it was found to have a beneficial effect on the human body.
